EXTENSION DOOR FOR GARAGE-'5 AND OTHER BUILDINGS Filed Dec. 8, 1936Patented Aug. 24, 1937 ?ATENT OFFICE EXTENSION DOOR FOR GARAGES ANDOTHER BUILDINGS Kilian H. Buettner, Baltimore, Md. Application December8, 1936, Serial No. 114,779 1 Claim. (01. 20-16) This invention relatesto improvements in garages and similar buildings, and has especialreference to the extension doors which permit the enlargement of saidgarages or buildings when 5 desired. There are a number of older garageswhich are not deep enough to accommodate modern automobiles, or two ofsaid automobiles, and which can be enlarged for their accommodation bythe use of my present invention.

The invention consists of the novel construction and arrangement of theparts and combination of parts hereinafter more fully set forth in thefollowing specification and pointed out in detail in the appended claim.

15 In the accompanying drawing:

Figure 1 is a front elevation of a garage having my invention appliedthereto.

Figure 2 is a vertical section of Figure l on the line 2-2 with thedoors in the extended position.

20 Figure 3 is a section on the line 33 of Figure 1 with the doors inthe extended position.

Figure 4 is a similar view to Figure 3 with the doors folded together ona line with the front of the garage.

25 Figure 5 is a section on the line 55 of Figure 4.

Referring to the accompanying drawing, forming part of thisspecification, and in which like reference numerals designate like partsthrough- 30 out the several views thereof, l designates the building and2 is a canopy, formed of metal or other suitable material, and securedto, and extending beyond the front of the building just above theopening thereof. Hinged to the build- 35 ing on each side of the openingthereof, are the doors 3 and hinged to said doors 3 are the doors ,4.The said doors 3 and 4 are adapted to close.

on a line with the front of the building which, when not in use, or whenbeing used for the purpose of enclosing a short car, as shown in Figure4 of the drawing. When the building is to be occupied by a car which istoo long for the build- 5 ing when the doors are in the position shownin Figure 4 of the drawing, the said doors are opened and broughttogether in the extended position as shown in Figure 3 of the drawing,thus affording an additional length to the garage, or building, asdesired. The doors can be locked in either of the positions shown inFigure 3 or 4 of the drawing. The said doors 3 and 4 are each providedwith a hinged drop 5 which can be lowered when the doors are in theextended position to close the space below the doors when there is anincline in the driveway 6 as shown in Figures 1 and 2 of the drawing.These doors 5 are hinged at 1 so that they can be folded up against thedoor when the latter are in the position shown in Figures 4 and 5 of thedrawing. When the doors are in the extended position the opening at thetop is covered by the canopy 2. 1

By the use of my present invention, a garage or other building in whichit is desired to place 5 an automobile, truck, or other vehicle, can belengthened to a considerable extent.

Having thus described my invention, what I claim is:

A garage, or other building, having an opening therein, a plurality ofhinged doors adapted to close the said opening either on a line with thebuilding or in an extended position, and a canopy extending from saidbuilding above said opening and adapted to .close the space above thedoors when they are in the extended position.
